Overview

Modern web apps are fast to build but slow to ship well. This course gives intermediate web developers the tools to measure, diagnose, fix, and,crucially, avoid web performance problems across network, rendering, JavaScript, and animation layers. With a mobile-first lens and hands-on practice in every session, students leave as evidence-driven engineers, not gut-feel optimisers.

Learning highlights

  • Hands-on practice integrated into every single session — no passive lecture days.
  • Twice-weekly homework reviewed in class, so confusion doesn't accumulate.
  • A full real-site audit in Session 14 — applying every tool and concept from the course.
  • Mobile-first framing throughout — device throttling, field data, and real-world constraints from day one.
  • Closes with "performance by design" — shifting from reactive debugging to proactive engineering habits.
